Abstract

A slip ring apparatus which includes a housing, a contact assembly recess defined by the housing, a slip ring rotor assembly contained within the interior of the housing adjacent to the contact assembly recess, a slip ring contact assembly mounted within the interior of the housing, wherein the slip ring contact assembly is insertable and removable from the interior of the housing via an exterior recess side of the contact assembly recess, and a hatch cover for covering the contact assembly recess, wherein the hatch cover is removable and replaceable via the exterior recess side of the contact assembly recess. A method of servicing a slip ring apparatus which includes removing a hatch cover, servicing the slip ring apparatus, and replacing the hatch cover, all via an exterior recess side of the contact assembly recess.

Claims23

Dependent claims

A slip ring apparatus comprising:

(a) a housing, wherein the housing has an exterior and an interior;
(b) a contact assembly recess defined by the housing, wherein the contact assembly recess has an exterior recess side which is accessible from the exterior of the housing and wherein the contact assembly recess has an interior recess side which is in communication with the interior of the housing;
(c) a slip ring rotor assembly contained within the interior of the housing, wherein the slip ring rotor assembly is adjacent to the interior recess side of the contact assembly recess, and wherein the slip ring rotor assembly is rotatable relative to the housing;
(d) a slip ring contact assembly mounted within the interior of the housing so that the slip ring rotor assembly is rotatable relative to the slip ring contact assembly, wherein the slip ring contact assembly is electrically connected with the slip ring rotor assembly, and wherein the slip ring contact assembly is insertable into the interior of the housing and is removable from the interior of the housing via the exterior recess side of the contact assembly recess;
and
(e) a hatch cover for covering the contact assembly recess and the slip ring contact assembly, wherein the hatch cover is removable and replaceable via the exterior recess side of the contact assembly recess.

3 more elements

A slip ring apparatus comprising:

(a) a housing, wherein the housing has an exterior and an interior;
(b) a plurality of contact assembly recesses defined by the housing, wherein the contact assembly recesses each have an exterior recess side which is accessible from the exterior of the housing and wherein the contact assembly recesses each have an interior recess side which is in communication with the interior of the housing;
(c) a slip ring rotor assembly contained within the interior of the housing, wherein the slip ring rotor assembly is adjacent to the interior recess sides of the contact assembly recesses, and wherein the slip ring rotor assembly is rotatable relative to the housing;
(d) a plurality of slip ring contact assemblies, wherein each of the slip ring contact assemblies has a corresponding contact assembly recess, wherein the slip ring contact assemblies are mounted within the interior of the housing so that the slip ring rotor assembly is rotatable relative to the slip ring contact assemblies, wherein the slip ring contact assemblies are electrically connected with the slip ring rotor assembly, and wherein each of the slip ring contact assemblies is insertable into the interior of the housing and is removable from the interior of the housing via the exterior recess side of its corresponding contact assembly recess;
and
(e) a plurality of hatch covers for covering the contact assembly recesses and the slip ring contact assemblies, wherein the hatch covers are removable and replaceable via the exterior recess sides of the contact assembly recesses.

3 more elements

A method of servicing a slip ring apparatus comprising a contact assembly recess defined by a housing, the contact assembly recess having an exterior recess side which is accessible from an exterior of the housing and an interior recess side which is in communication with an interior of the housing, a slip ring rotor assembly contained within the interior of the housing adjacent to the interior recess side of the contact assembly recess, wherein the slip ring rotor assembly is rotatable relative to the housing, a slip ring contact assembly mounted within the interior of the housing so that the slip ring rotor assembly is rotatable relative to the slip ring contact assembly, wherein the slip ring contact assembly is electrically connected with the slip ring rotor assembly, and a hatch cover covering the contact assembly recess and the slip ring contact assembly, the method comprising:

(a) removing the hatch cover via the exterior recess side of the contact assembly recess;
(b) servicing the slip ring apparatus via the exterior recess side of the contact assembly recess;
and
(c) replacing the hatch cover via the exterior recess side of the contact assembly recess.
